Cov txheej txheem yas extrusion yog cov txheej txheem ncaj qha uas cuam tshuam nrog cov pob zeb yaj (cov khoom siv thermostat raw), lim nws thiab tom qab ntawd tsim nws rau hauv cov duab muab.Lub rotating ntsia hlau pab nyob rau hauv thawb down ib tug rhuab chim rau ib tug muab kub.Cov yas molten yog dhau los ntawm kev tuag los muab cov khoom kawg nws cov duab lossis profile.Lim muab cov khoom kawg nrog kev sib xws.Ntawm no yog ib tug ceev ceev ntawm tag nrho cov txheej txheem.
Kauj ruam 1:
Cov txheej txheem pib los ntawm kev qhia cov khoom yas nyoos xws li granules thiab pellets rau hauv lub hopper thiab pub rau hauv extruder.Colorants lossis additives yog ntxiv yog tias cov ntaub ntawv raw tsis muaj qee yam.Lub taub hau tig ua kom yooj yim rau kev txav ntawm cov khoom nyoos los ntawm cov cua sov cylindrical chamber.
Kauj ruam 2:
Lub hopper cov ntaub ntawv raw ces ntws los ntawm lub caj pas pub rau ib tug loj spinning ntsia hlau nyob rau hauv ib tug kab rov tav chim.
Kauj Ruam 3:
Cov ntaub ntawv sib txawv muaj cov khoom sib txawv, nrog rau qhov kub thiab txias.Raws li raw cov ntaub ntawv hla dhau los ntawm lub rhuab chamber, nws yog rhuab mus rau nws tshwj xeeb melting kub, xws li ntawm 400 mus rau 530 degrees Fahrenheit.Cov resin yog sib xyaw kom huv si los ntawm lub sijhawm nws mus txog qhov kawg ntawm lub hau.
Kauj Ruam 4:
Ua ntej cov resin yog dhau los ntawm kev tuag los tsim cov khoom kawg ntawm cov duab, nws dhau los ntawm ib qho screen reinforced los ntawm lub phaj breaker.Lub vijtsam tshem tawm cov kab mob lossis qhov tsis sib xws uas tej zaum yuav nyob hauv cov yas yaj.Cov resin yog tam sim no npaj tuag raws li nws tau pub rau hauv kab noj hniav kom txias thiab tawv.Cov dej da dej los yog cov rolls txias tuaj yeem pab ua kom ceev cov txheej txheem txias.
Kauj ruam 5:
Cov txheej txheem yas profile extrusion yuav tsum nyob rau hauv xws li ib txoj kev uas cov resin ntws smoothly thiab tusyees nyob rau hauv ntau theem.Qhov zoo ntawm cov khoom kawg yog nyob ntawm qhov sib xws ntawm tag nrho cov txheej txheem.
Cov khoom siv raw siv hauv cov txheej txheem yas extrusion
Cov ntaub ntawv yas sib txawv tuaj yeem ua kom sov thiab tsim rau hauv qhov profile txuas ntxiv.Cov tuam txhab siv ntau yam khoom siv raw, suav nrog polycarbonate, PVC, cov ntaub ntawv siv dua tshiab, nylon thiab polypropylene (PP).
